An arrangement for an axle (4) which is anchored at two points situated at the ends of the axle (4), preferably in mounting cheeks (1, 2) or the like provided with through-bores (5, 6) for the axle (4). Anchoring is accomplished by means of nuts (7, 8) which can be screwed on outside the fixing points. On a central cylindrical part (9) the axle is designed to have a bearing (10) mounted on it which is fixed by means of spacer elements (11, 12) disposed on the axle (4) and bridging the distance between the respective fixing points and the bearing (10). According to the invention one (11) of the spacer elements (11, 12) is disposed fixed relative to the cylindrical part (9) of the axle (4). The arrangement comprises two expanding sleeves (13, 14) which can be inserted in the said through-bores (5, 6) and have inwardly-facing and/or outwardly-facing conical shaping. In a zone (16, 17) at the respective fixing points the axle (4) and/or the through-bores (5, 6) have corresponding conical shaping so that the respective expanding sleeves (13, 14) act as annular wedges with their apex pointing towards the cylindrical part (9), i.e. so that by means of associated nuts (7, 8) the respective expanding sleeves (13, 14) can be caused to expand against or be pressed in by the wall of the through-bores (5, 6) thereby accomplishing the anchoring of the axle (4). |
